The general experience of women from childbirth process is an important outcome. The quality of these experiences affect the mother and her babies’ health and their relationship, sexual activity and desire to having next child in future. Hot shower and intravenous injection of hyoscine are utilized to promote childbirth experience and increased satisfaction of childbirth; however, their effects are not thoroughly investigated. This study was performed with aim to assess the effects of hot shower and intravenous injection of hyoscine on childbirth experience in nulliparous women.
This randomized controlled clinical trial was conducted on 162 nulliparous women who were hospitalized in 29-Bahman hospital of Tabriz in 2015. The participants were assigned into 3 groups of 54 cases (intravenous hyoscine, hot shower, and control) by block randomization. In the intervention groups, hyoscine and hot shower were applied at dilatation of 4 cm and 7 cm. The control group received routine cares. Childbirth experience questionnaire was completed by the participants 12 to 24 hours after childbirth; the higher score showed better experience. Data were analyzed by SPSS software (version 20) and One-way ANOVA and Chi-square, Fisher-Exact, and Kruskal-Wallis tests. P The mean score of childbirth experience was 44.3±5.7 in the hyoscine group, 42.3±11.7 in the hot shower group and 39.0±10.6 in the control group. The mean score of childbirth experience was significantly higher in the hyoscine group (P= 0.014) and the hot shower group (P= 0.046) compared with the control group. However, there was no significant difference between two intervention groups (P=0.401). There was no significant difference between the groups in terms of satisfaction of childbirth and oxytocin consumption (P>0.05).
Using of non-pharmacological method of hot shower can improve childbirth experience similar to hyoscine group; therefore, using of this non-pharmacological supportive method is recommended to the mothers.
